Review what we have covered in this chapter.

In this chapter, we focused on translating the final API prototype into an actual working implementation of the Onboarding API. To do that, we used a simple API library called DARRT that was built with Node.js, an Express.js HTTP library, and the EJS template library.

The DARRT library leads developers to translate designs into five parts: data, actions, resources, representations, and transitions. The first three parts are common in all web API approaches. The last two are added to improve the quality of the implementation, especially to support the use of links and forms. Moreover, we also covered how links and forms make up the distinguishing elements of APIs that are built using the principles of web development.
